It was a physicist who proposed this ridiculous idea. How about "I'm no meteorologist, but...".

Harold Brooks is pretty much the world's foremost expert on tornado climatology. Not only would it not work, and cost more than the GDP, but it would have devastating local effects for those who lived near the wall.

Building a wall like that would induce all sorts of other weather effects.

The first one I can think of is all of the land west of the wall would get an increase in rain due wet air having to drop rain in order to gain elevation to cross the wall. Then the land immediately east of the wall would dry out due to lack of rain.

To say nothing of the weird sunlight problems that would occur on the west side of the wall.

Poor reading comprehension. The proposed walls run East-West, not North-South.
